Preparation of hierarchical MoS2 microsphere/BN composites for microwave absorption and thermal management

  • The increase in the utilization of infrared heat detection technology in military applications necessitates research on composites with improved thermal transmission performance and microwave absorption capabilities. This study satisfactorily fabricated a series of MoS2/BN-xyz composites (which were characterized by the weight ratio of MoS2 to BN, denoted by xy:z) through chemical vapor deposition, which resulted in their improved thermal stability and thermal transmission performance. The results show that the remaining mass of MoS2/BN-101 was as high as 69.25wt% at 800°C under air atmosphere, and a temperature difference of 31.7°C was maintained between the surface temperature and the heating source at a heating temperature of 200°C. Furthermore, MoS2/BN-301 exhibited an impressive minimum reflection loss value of −32.21 dB at 4.0 mm and a wide effective attenuation bandwidth ranging from 9.32 to 18.00 GHz (8.68 GHz). Therefore, these simplified synthesized MoS2/BN-xyz composites demonstrate great potential as highly efficient contenders for the enhancement of microwave absorption performance and thermal conductance.
